Orionids from Taipei in 2026

Orionids from Taipei: the short answer

The Orionids reaches maximum at 02:23 local time on 22 October 2026 over Taipei, Taiwan (25.1°N, 121.53°E, 5 m). The radiant culminates 80.6° high at 04:14 and the useful window runs 02:00–05:00, with an ideal-sky ceiling of 19.7 meteors an hour.

That ranks it 4th of twelve from Taipei this year, behind the Geminids (148.8/h) and the Perseids (79.4/h).

The radiant track over this city

Orion carries the radiant. From Taipei it clears the horizon at 21:45 on a bearing of 73° (ENE), reaches 80.6° at 04:14 in the south, and drops back below the horizon at 10:44. Within the observing window it peaks at 80.0°.

When it gets dark here

Sunset over Taipei is 17:21, civil twilight ends 17:45, and the sky reaches astronomical darkness — Sun 18° down — at 18:38. It holds until 04:38, with sunrise at 05:55: 10 hours of real darkness inside 12 h 34 min of night.

Local solar midnight, the true middle of the night, falls at 23:38 here rather than at 00:00: Asia/Taipei runs 6 minutes behind mean solar time at 121.53°E. That offset is why the best hour on this page is not the hour you would guess from the clock.

What the Moon does here

Moonlight is the limiting factor on this night from Taipei. The Moon is 78% lit and only 4 of 12 sampled hours are moon-free. Moonrise 14:15. Moonset 01:51. At the best hour it stands 28.5° below the horizon, pulling the limiting magnitude down to 6.50.

Why 20 an hour and not 20

Zenithal hourly rate 20, population index 2.5, entry speed 66.1 km/s — very fast. Those are stream constants. What changes from city to city is the geometry: at 80.0° of radiant altitude and limiting magnitude 6.50, Taipei converts that ZHR into about 19.7 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 18:00 (radiant -42.0°) to 1.8 at 05:00 (radiant 75.9°), peaking at 19.7. That spread across 12 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Comet 1P/Halley and is listed as active 2 October to 7 November, so 22 October 2026 is the best night from Taipei rather than the only one.

Watching from around Taipei

Taipei, Taiwan is the 33rd largest of the 300 cities covered here, with a population of 7.87 million at 5 m above sea level. The nearest other cities on the site are Taichung (132 km SW), Fuzhou (249 km WNW), Putian (257 km W) — close enough that the radiant altitudes barely change, far enough that sunset and moonrise do.

What this page does not know

Light-pollution data for this location is not connected yet. Rates on this page are computed against the reference rural sky the zenithal hourly rate is defined for (naked-eye limiting magnitude 6.5); they are not a claim about how bright the sky is where you are standing. Once the light-pollution layer is connected these figures will be recomputed for the local sky and will generally fall.

Cloud cover is a forecast, not a constant, so it is resolved when you load the tonight card and is deliberately absent from this prerendered page — the hourly table shows "unavailable" rather than assuming clear skies. Meteor outbursts, local terrain and building horizons are not modelled.

A single observer with an unobstructed horizon typically records 30–50% below the ideal-sky figure. Give your eyes twenty minutes to adapt, keep bright screens away, look about halfway up the sky rather than straight at the radiant, and count for a full hour before judging a shower.
